Many digital copying devices produce copied pages at a different rate than their nominal speed due to various factors. These include, but are not limited to, job characteristics (black-and-white versus color); the number of pages to be copied; single-sided or double-sided output; quality setting; number of copies; paper type and size; document content, and document complexity.

ISO/IEC 29183 specifies a method for measuring the productivity of digital copying devices using varying characteristics on plain paper in default mode. It is applicable to black-and-white and color devices, regardless of print technology (e.g. inkjet, laser, etc).

ISO/IEC 29183 allows manufacturers of digital copying devices to measure the productivity of different digital copying devices with a standard measurement method.

Testing Overview

Tests are conducted with the device set to plain paper with the quality level at the factory default. For color devices, black-and-white tests are run by setting the device to copy in black-only mode. Testing is done 1:1 mode.

Each of the four test documents are copied from the flatbed scanner with the number of copies varied to create copy jobs of arbitrary length.

Test Documents

Three different job lengths are tested

Short Jobs

1 copy

Medium Jobs

1 copy plus about 30 seconds of additional copying

Long Jobs

1 copy plus about 4 minutes of additional copying

Three different methods of timing are used

Time from the initiation of the copy job until the first copy lands in the output tray

The time resulting from this measurement is referred to as First Copy Out Time (sFCOT).

Time from the initiation of the copy job until the last copy of the job lands in the output tray

A PPM resulting from this measurement is referred to as Effective Throughput (sEFTP).

Time from when the first copy lands in the output tray until the last copy of the job lands in the output tray

A PPM resulting from this measurement is referred to as Estimated Saturated Throughput (sESAT).

The following results are reported for each page as well as the average of all pages

sFSOT for the short job.

sEFTP for the short, medium, and long jobs.

sESAT for the medium job. HP generally advertises the average sESAT PPM.

B&W maximum speed footnote

The ISO/IEC 29183 report for some products may include a footnote indicating that the B&W copy speed is limited to a maximum speed for some countries. If so, the following countries are affected:

What is ISO?

ISO (International Organization for Standardization) is the world's largest developer and publisher of International Standards.

ISO is a network of the national standards institutes of 157 countries, one member per country, with a Central Secretariat in Geneva, Switzerland that coordinates the system.

ISO is a non-governmental organization that forms a bridge between the public and private sectors. Many of its member institutes are part of the governmental structure of their countries, or are mandated by their government. Other members have their roots uniquely in the private sector, having been set up by national partnerships of industry associations.

This structure ISO enables a consensus to be reached on solutions that meet both the requirements of business and the broader needs of society. For more information on ISO see www.iso.org.
